When selecting barebox in menuconfig, BR2_TARGET_BAREBOX_IMAGE_FILE will
be empty by default, which causes Buildroot to install whatever the
barebox-flash-image symlink points at for barebox versions >= v2012.10.0.
This is an outdated fallback, because barebox-flash-image is only valid
when the barebox build produces a single binary. Virtually all new
defconfigs added in the last couple of years are multiconfig
(CONFIG_PBL_IMAGE=y) however, meaning that a single imx_v7_defconfig
or multi_v8_defconfig will produce many images that support different
boards or even platforms.
As there is no single valid target for barebox-flash-image to point at
in this case, this symlink will point at a non-existing
'multi-image-build' to alert the user to this fact.
As replacement for barebox-flash-image, barebox commit 550cf79c216a
("Make list of flash images and fix link all single image cases") first
released with v2015.12.0 creates a barebox-flash-images file with a list
of all images built by barebox.
Have buildroot use that file as a fallback before trying
barebox-flash-image to have a fallback that works for any recent barebox
defconfig as well.
